Newton's Laws of Motion

The first law of motion is Inertia.
Inertia means that something in motion will stay in motion unless an unbalanced force affects it. Example: the soccer ball would keep going but the soccer goal stops it.

Inertia also means the same for an object at rest. An object at rest will stay at rest unless acted on by an unbalanced force.
Example: Your chromebook is resting on your desk. It will stay that way forever until you pick it up.

Newton's 1st Law of Motion

Newton's 2nd law of motion is about unbalanced forces causing motion. Basically the more massive an object the more force must be applied to move the object with the same acceleration as a less massive object. Example: The car requires much more force than the lawn mover to move them both at 1 m/s.


If there is an unbalanced force that means there is acceleration. Vice versa, if acceleration is present, there is an unbalanced force involved.

Newton's 2nd Law of Motion

The triangle, similar the distance, time, and speed triangle, tells you how to solve for Force, Mass, or Acceleration. Mass x Acceleration = Force. So as mass increases, the Force must also increase by the same proportions to keep it the same acceleration. This works the other way as well. If acceleration increases, force must also increase.

Newton's 2nd Law of Motion
Cont.

​The 3rd law is for every action there is an equal an opposite reaction. This means for every force applied, there is a force applied in the opposite direction. Some examples include. Throwing a ball at the ground and it bouncing back up to you.
Another example is gravity pulling you to the center of the Earth, but the ground pushing back up on you so you do not fall through the ground.
